// WikiSpaceCreate wraps wiki.spaces.create. The raw API only takes two
// optional string fields, so the shortcut's value is flag ergonomics
// (no hand-written --params JSON), output flattening (data.space.* lifted
// to the top level), and a dry-run preview.
//
// The API only accepts a user access token (no tenant/bot), so AuthTypes is
// user-only — the framework's CheckIdentity rejects --as bot for us.
